Gets hot when heated to extract moisture so use gloves to remove from microwave or just let it sit for a few minutes to cool off. Works well,within the first several days, my moisture meter recorded a drop in the gun safe of about 30 points from 70 percent to 40. I have a goldenrod in there so that indicates to me that it was not doing a great job. I just throw this in on the shelf and let it do its thing.
Doesn't take up any room at all. Almost like throwing a couple of socks in there.
This product easy to recharge, compact size for under seat gun safes or small handgun safe. Keeps safe dry for many days, depending on location of safe. I recommend this for gun owner who have a gun safe exposed to outside conditions(ex.garage) or in areas of high humidity.
